Patent GB-2117371-A (GB)
Title: Process for producing cement clinker
Inventor: NUDELMAN BORIS IZRAILOVICH
IPC: C04B7/44
Filed: 1982-03-25
Abstract: A process for producing cement clinker comprises dry grinding of raw components, mixing the resultant raw meal with a solid fuel, pelletizing the resultant batch with the addition of calcium chloride thereto, subsequent heat treatment of the resultant pellets of a raw mix in their dense layer in zones of drying, roasting by burning a fuel over the surface of said layer with drawing fuel combustion products therethrough and removal of exhaust gases released therefrom, and cooling the resultant clinker. According to the invention, the temperature of fuel combustion products over the surface of the dense pellet layer is maintained at 1150-1250 DEG C within a portion of the roasting zone extending over a length of maximum one half of the roasting zone length, with subsequent lowering of this temperature to between 900 and 1000 DEG C in the direction toward the cooling zone.
Patent GB-2120840-A (GB)
Title: Contrast improvement in vacuum image display devices
Inventor: WOODHEAD ALFRED WALTERS
IPC: H01J29/28
Filed: 1982-05-12
Abstract: Loss of contrast due to back- scattered electrons from a fluorescent screen of a vacuum image display device can be reduced by applying a thin metallic reflecting film 34 to the back of the fluorescent screen and applying a layer 36 of an element of low atomic number and low back-scattering coefficient, for example carbon, to the reflecting layer. The thickness of the reflecting film is sufficient to obtain the desired reflection and to provide an impervious layer to prevent the element of low atomic number from passing through the metallic film. By applying a desired thickness of the element then an acceptable compromise between the back- scattered contribution and the primary light output can be reached for any given operating voltage. For a reflecting film of aluminium of 19  mu g/cm<2> thickness an empirical relationship to determine the operating conditions to give the required contrast performance is  VC = 0.38VA + K where VC is the cut-off voltage on the screen, VA is the electron acceleration potential and K is a constant depending on the contrast C, i.e. the ratio between light output due to back-scattered electrons to light output due to primary electrons. <IMAGE>
Patent GB-2100552-A (GB)
Title: T.D.M. exchanges
IPC: H04Q11/04
Filed: 1982-05-24
Abstract: A coupling arrangement KM for a digital exchange system, for example working according to the PCM technique, is constructed with a combination of time-and space multiplexing. Thus there are firmly assigned to the individual exchange devices the parts of the coupling circuit that are necessary for through-connection of the data paths. At an interconnection of time- and space multiplexing means there is inserted in the transmitting direction an intermediate store ZS which guarantees reception of the data bits in a way that is not critical from a time point of view, by the receiving synchronising signal being displaced by a clock period that is delayed with respect to the transmitting synchronising signal. <IMAGE>

Title: Road man-hole cover or gully grid and supporting frame
Inventor: HAUER JEAN-CLAUDE
IPC: E02D29/12
Filed: 1982-06-11
Abstract: A removably-hinged self-locking manhole cover or gully grid 3 rests on inclined rear support surfaces 13A, 13B in its frame 1 so that as it settles under load it moves forwardly to engage a fixed locking projection 23 thereon under a fixed frame projection (not shown). As shown. the frame has two downwardly inclined slots 15 receiving short and long lateral lugs 27 at the rear of the grid so the latter can pivot in the frame and be removable. The downwardly sloping support surfaces 13A, 13B at the rear of the frame direct the grid forwards therein as it settles, while the front of the grid rests on two horizontal support projections at the front of the frame and on two inclined corner projections for lateral centering. The locking projection 23 (on the grid front) has a sloping upper face to engage under the sloping face of an overhanging projection on the skirt 4 to lock the grid to the frame. <IMAGE>

Title: Process for stabilising vinyl chloride polymers and copolymers
Inventor: BOURDAUDUCQ PAUL
IPC: C08K5/524
Filed: 1982-07-02
Abstract: A process for the stabilisation of a polymer or copolymer of vinyl chloride, which process comprises incorporating a tertiary phosphite of isotridecyl alcohol in the polymer or copolymer, in an amount of from 0.1 to 5% by weight based on the weight of the polymer. The stabilising phosphite is advantageously used in conjunction with Ba-Cd or Ba-Zn soaps. It may also be combined with an epoxide such as epoxidised soya oil and/or an amino additive such as tris- isopropanolamine. The resultant plastics have an excellent long-term stability which is superior to that obtained when other trialkyl or alkylaryl phosphites are used.

Patent GB-2112933-A (GB)
Title: Positioning apparatus
Inventor: WALTHER ADRIAAN
IPC: G05D3/12
Filed: 1982-12-14
Abstract: A semiconductor wafer (11) carrying a fresnel zone target (17) is precisely positioned in a projection printing system by illuminating the target with coherent light from a laser (21) thereby to generate first order point images (PA and PB) above and below the wafer surface. These points are re-imaged by a re-imaging system of mirrors (27, 39) lasers (31, 35, 37, 38) and a beam splitter (33), at essentially equal magnification, onto a pair of photoelectric detectors (41, 43) thereby to generate output signals each of which includes an error component indicating the relative position of the respective projected point image (PA'', PB''). The position of the wafer is then controlled by X and Y axis micro-positioners (47 etc.) in response to the sum of these signals computed by summing and servo electronics (45) to seek a position where the error components are equal and opposite. As translational mispositioning of a wafer produces additive components in the detector signals and tilting of the wafer surface produces offsetting components, positioning errors due to tilt are reduced. <IMAGE>
